Explanation of phylogenetic trees
Morphology
Like all arthropods, insects have a hard external shell, or exoskeleton, made mostly of chitin. Although there are others, the characteristic feature uniting all insects is the segmentation of the body into three sections, or tagmata. These are namely: the head, thorax and abdomen.
Distribution
Insects occur worldwide in nearly all environments except for the open ocean.
